WOODFORD SHANNON, OF LOUISVILLE, KNTUCKY:

SPRING-BED.

Specification of Letters Patent.

Application filed August 17, 1911.

Patented Mar. 10, 1914. Serial No. 644,495.

To all altem it may concern Be it known that I, lVooDronD SHANNON, a citizen ot' the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented a new and useful Spring-Bed, of which the following is a specification.

My invention relates to spring beds and particularly to those forms with a series of spiral springs.

It has for its object to provide various improvements lin the structure of the springs, in the frame support, and in the covering.

My invention consists of novel features and parts and combinations of the same which will be more'fully set out hereinafter and then pointed out in the claims.

A practical embodiment thereof is shown in the accompanying drawings, in which- Figure l is a plan view; Fig. 2 an end elevation; Figs. 3 and 4, detail views; Fig. 5, a perspective view' of the clip; Fig, 6, a detail perspective view of the spring structure; and Fig. 7, a detail View of the means for attaching the cover.

My invention consists first in a novel combination of a tensioning device and the crossrods of the upper deck construction, and their attachment, to the side frames of a bed bottom support, so as to hold the spring work with relative rigidity against side motion, and at the same time permit practical freedom of compression of the separate spirals in such spring Work.

My invention further consists in a novel connection between the spirals of the spring work with the supporting bars of the bed bottom support. IVIy invention further consists in a cellapsible parallelogram extension attached to side frames of said bed bottom support. swinging therefroml in horizontal planes.

My invention further consists in a novel extension frame, provided with means for detachably 'fastening the cover oit' the bed bottom of springs, as shown in Figs. 3 and 1l.

As embodied in the drawings, vthe series ot spiral springs l are supported in the frame consisting of the side angle bars 'lil and the connecting under-hung transverse bottom supporting bars 2. These supporting bars are preferably vertically disposed under the springs. The bottom ring of the spiral l is connected toa bar 2 by the clip both slats 2 and rods 18 of such degree as to hold all of said elements rigidly in place. In the manufacture of what are commonly known as double deck springs, heretofore the practice has been to provide various devices to prevent the sidewise' displacement of the high spirals necessarily employed, such devices being continuous and coterminous with the length and width of the high spiral spring work. Such devices have proven effective to prevent sidewise displacement of the separate spirals, but in practical use there has been found an objectionable side motion of such construction. To prevent such side motion, I have me diately attached the elements 7 by the helical springs 8 and their associated straps to the angle side frames 11. tended the rods 7 but partially across the double deck spring work, connecting the inner ends of such rods 7 by the helical springs 9, all under sufficient tension to withstand the strains tending to produce side motion, but having suilicient elasticity to permit practical freedom oi. compression of the lower ends of the spirals l. To further maintain the rods 7 in proper position I employ the longitudinal rods 14, inserting them through the eyes of the rods 7, so that the pressure of the rods 14 upon the eyes of the rods 7 will prevent any torsion of said rods out of their proper planes.

The combination of these rods with the spirals l is disclosed in U. S. Letters Patent to me Number 929,333.

The swinging parallelogram extension is attached to the main side angle bars l1 and consists of the bars (i, pivoted to the short arms 5, which are in turn pivoted to the under side of the angle bars 1l. By means of the straps connecting with the helicals 8, I hold the side spirals 3 firmly in position upon the flat tops of the side angle bars l1.

I support the covering 1Q by the wire I have also eX-,

c hold ,the studs in place.

I do not limit myself to the exact form in which my invention is herein disclosed further than is indicated in the claims which follow. I claim: 1. A spring bed comprising a plurality i of spiral springs, rods passing therethrough adapted to support said springs against lat` eral displacement, and resilient means for 'holdingsaid lrods under longitudinal. tension.

2. A spring bed comprising a plurality of spiral springs, a stiff side frame placed above the bottoms of said springs, rods passing through said springs and connected with said side frame adapted to support said springs against lateral displacement, and resilient Ameans for holding said rods under longitudinal tension.

3. A spiralspring, a supporting inember bearing at two opposite points of the face, of a ring of said spring and being narrower than the diameter of said ring, a key member binding said ring on the face opposite to that supported by the said supporting member and at points between the points of support; and a clip straddling said supporting member and bent overY said key member on opposite sides of said supporting member at points within said ring.

4. A spring bed comprising a series 'of springs, an outside support on the upper l surface thereof, an outside lower support, an extension frame therefrom approximately parallell to said upper support, and a cover drawn over-said upper frame and fastened to said lower extension,

5. A spring bed comprising a series of springs, an outside support on the upper surface thereof,'an outside lower support, an `eXtensionframe therefrom provided with holes, and a cover provided with resilient studs and drawn over said upper frame and fastened to said lower extension by said studs.

6. A spring bed comprising a rigid bed bottom support, a bed bottom of springs built thereupon, and a swinging parallelo- ,gram extension from said bed bottom support adapted to change the Ywidth of said 'bed bottom support.
